Biological information processing device and biological information processing method

A biological information processing device comprising:

• an image inputter configured to input image data;
• a selector configured to select image ranges of processing targets from the image data which is input from the image inputter;
• an extractor configured to extract signals indicating a predetermined range of the image data which is input from the image inputter;
• and
• a plurality of filters configured to respectively output signals corresponding to different coefficients among the signals indicating the predetermined range extracted by the extractor by using the different coefficients
• a plurality of estimators respectively corresponding to the plurality of filters, and configured to estimate pulse rates of the processing targets corresponding to the image ranges on the basis of image data of the image ranges of the processing targets selected by the selector, the plurality of estimators further configured to estimate pulse rates of a person on the basis of output signals of at least one cycle from the corresponding filters and input intervals of frames of the image data corresponding to the output signals of at least one cycle;
• a detector configured to perform relative comparison between the pulse rates of the processing targets estimated by the plurality of estimators and thus detect a target which is abnormal or a target requiring special attention;
• and
• an outputter configured to:
• output information regarding the target which is abnormal or the target requiring special attention detected by the detector,
• select any one of the plurality of pulse rates estimated by the plurality of estimators according to the output signals from the plurality of filters, and
• output the selected pulse rate.
